Shimano ULTEGRA SM-BBR60 BSA Hollowtech II Bottom Bracket
Shimano ULTEGRA SM-BBR60 BSA Hollowtech II Bottom Bracket
Shimano XT Hollowtech II BB-MT800 bottom bracket for Ultegra FC-R8000/6800, 105 FC-R7000/5800 and GRX FC-RX810 cranksets.
The concept of HOLLOWTECH II technology is focused on producing a superior crankset which will maximize a rider’s power transfer. The rigidity of the crankset ensures pedaling efficiency while its weight, a key element of the crankset, you want light, aids in cycling longer distances over which the rider needs to pedal more. Naturally, SHIMANO strove for the optimum balance between the conflicting needs of stiffness while producing a lightweight crank. HOLLOWTECH technology is an ultra-lightweight hollow crankarm created by SHIMANO with the company’s own proprietary forging technology that also maintains rigidity. The addition of HOLLOWTECH II technology integrates the bottom bracket axle with the right crankarm for more stiffness and a weight savings to achieve a high-dimensional balance. Its outboard bottom bracket bearing system provides better weight distribution and more pedaling stability, allowing for more efficient power transfer.

Quality and easy installation
Tutto perfetto. Solita qualità Shimano e spedizione veloce.
Montaggio estremamente semplice, eccellente realizzazzione costruttiva sia nei materiali che nella compattezza.
Über die Langlebigkeit des Lagers kann ich noch nichts schreiben, aber der Tausch gegen das alte Lager ist für jeden machbar und erfordert keine besonderen Schrauberfähigkeiten. Das das so leicht geht hatte ich mir nicht vorgestellt. Top!!
Il movimento centrale viene senza distanziali
